[0002] In glass production, it is necessary to transport some powdered materials, such as petroleum coke powder and gravel. The petroleum coke powder and gravel are transported from the storage tank to the top by a bucket elevator, and then flow into the Y-shaped lower hopper. Then, they slide down to the V-shaped conveyor belt below under the action of gravity for transportation. However, due to dryness or other reasons, the petroleum coke powder and gravel have poor fluidity and are easily accumulated on the inclined wall of the Y-shaped lower hopper, resulting in slow flow. In severe cases, the Y-shaped lower hopper may be blocked, and the staff need to continuously knock on the outer wall of the Y-shaped lower hopper to shake off the powder, which seriously affects the production efficiency and increases the labor intensity of the workers.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The following describes an embodiment of the present invention based on its overall structure.

[0027] The specific implementation of the utility model is as follows:

[0028] See Figure 1-Figure 7 The utility model provides a powder material hopper for preventing powder material from being blocked, comprising:

[0029] A dust cover 1 is provided on the powder conveyor belt 2, and a discharge port 3 is provided in the middle of the dust cover 1;

[0030] The lower hopper 4 is a Y-shaped lower hopper with a double feed port, and the lower hopper 4 includes a manifold 41 connected to the feed port and two feed inclined pipes 42 provided on both sides of the top of the manifold 41;

[0031] A lining plate 5, the lining plate 5 being detachably mounted on the guide inclined wall of the feed inclined pipe 42;

[0032] A material-splitting baffle 6 adapted to the upper surface of the powder conveyor belt 2 is provided in the dust shield 1 in front of the material discharge port 3 , and a material-passing hole 7 is provided in the middle of the material-splitting baffle 6 .

[0033] In the powder lower hopper of the present invention, which prevents powder from being blocked, the powdered material conveyed by the bucket elevator or other conveyor belt flows into the feed inclined pipe 42 of the lower hopper 4, and the powdered material flows on the guide inclined wall of the feed inclined pipe 42. Since a smooth lining plate 5 is provided on the guide inclined wall, the powdered material can flow quickly on the smooth lining plate 5 without accumulation and blockage on the guide inclined wall, thereby ensuring that the powdered material can smoothly slide onto the powder conveyor belt 2 in the dust cover 1;

[0034] Moreover, the liner 5 is a detachable structure. When the liner 5 is worn, the liner 5 can be replaced regularly. The liner 5 can protect the inner wall of the feed inclined pipe 42 and prevent the guide inclined wall of the feed inclined pipe 42 from being worn and the need to replace the entire feed inclined pipe 42.

[0035] A material leveling baffle 6 is provided in the dust cover 1 in front of the discharge port 3. The materials sliding down from the feed inclined tubes 42 on both sides of the Y-shaped discharge hopper are easily accumulated on the side of the powder conveyor belt 2 under the action of inertia. When there is a difference in the flow rate of the materials entering from the feed inclined tubes 42 on both sides of the Y-shaped discharge hopper, the discharge will be eccentric, and there may be more on one side and less on the other side. The powdered materials on both sides of the powder conveyor belt 2 can be blocked by the material leveling baffle 6, and the materials accumulated on both sides of the powder conveyor belt 2 will flow to the middle of the conveyor belt. The material passing hole 7 provided in the middle of the material leveling baffle 6 can allow the materials accumulated in the middle of the conveyor belt to pass through, thereby ensuring that the center of gravity of the materials is in the middle of the belt, and can automatically correct to prevent the conveyor belt from deviation.

[0036] In a preferred embodiment of the present invention, the lining plate 5 is a smooth plastic plate, which has good wear resistance, low manufacturing cost and low maintenance cost.

[0037] A preferred specific embodiment of this embodiment is that a plurality of spring telescopic rods 8 are provided on the guide inclined wall of the feed inclined tube 42, and the telescopic sections of the plurality of spring telescopic rods 8 are fixedly connected to a mounting plate 9. The liner 5 is detachably mounted on the mounting plate 9 by bolts, and the upper and lower ends of the liner 5 are mounted with elastic steel sheets 10 that can abut against the guide inclined wall of the feed inclined tube 42; in this embodiment, the mounting plate 9 can vibrate with the spring telescopic rods 8, and the liner 5 is mounted on the mounting plate 9. When the liner 5 is subjected to the pressure of the powdered material, the vibration of the liner 5 will shake up the powdered material on the liner 5, avoid the powdered material from docking, and improve the fluidity of the powdered material. The elastic steel sheet 10 can undergo elastic deformation to ensure that the elastic steel sheet 10 can maintain contact with the guide inclined wall, so that the powdered material can slide smoothly onto the liner 5.

[0038] In a preferred embodiment of the present invention, the elastic steel sheet 10 is a zigzag steel sheet structure, and the zigzag steel sheet structure is fixedly connected to the liner 5 via a bolt structure.

[0039] A preferred specific embodiment of this embodiment is that the material passing hole 7 is an arch structure provided in the middle of the material leveling baffle 6 .

[0040] A preferred specific embodiment of this embodiment is that the material leveling baffle 6 is a V-shaped plate structure with both sides bent backward. The two sides of the V-shaped plate structure can guide the powdered material on both sides of the conveyor belt to the middle, so that the center of gravity of the material is located in the middle of the conveyor belt.

[0041] A preferred specific embodiment of this embodiment is that the powder conveyor belt 2 includes a frame 21, inclined rollers 22 symmetrically arranged on both sides of the top of the frame 21, a positioning roller 23 arranged at the bottom of the frame, a V-shaped conveyor belt 24 and a conventional drive device, and the bottom of the side panels on both sides of the dust cover 1 are bent inward to provide an inclined baffle 16 adapted to the inclined surface of the V-shaped conveyor belt 24. The inclined baffle 16 is adapted to the inclined surface of the V-shaped conveyor belt 24, which can prevent the powdered material from flowing out and avoiding pollution to the factory building.

[0042] A preferred specific embodiment of this embodiment is that support bases 11 connected to both sides of the frame 21 are provided on both sides of the dust shield 1. The support bases 11 include upright posts 12 fixedly connected to the frame 21 and crossbeams 13 fixedly connected to the sides of the dust shield 1. The upright posts 12 are provided with a plurality of mounting holes evenly arranged vertically. The crossbeams 13 are mounted on the upright posts 12 by bolts in conjunction with the mounting holes and can be adjusted up and down. The dust shield 1 is fixedly mounted above the powder conveyor belt 2 via the support bases 11. The height of the dust shield 1 can be adjusted by adjusting the height at which the crossbeams 13 are mounted on the upright posts 12. The dust shield 1 has good adaptability and is easy to adjust. When it is necessary to inspect the internal structure of the dust shield 1, the dust shield 1 can be raised, and then the structures such as the material shaving baffle 6 inside the dust shield 1 can be inspected, making it easy to replace and maintain the material shaving baffle 6.

[0043] A preferred specific embodiment of this embodiment is that the manifold 41 and the feed inclined tube 42 are square tube structures, and a motor 14 is provided on one side of the feed inclined tube 42. The output shaft of the motor 14 extends into the feed inclined tube 42 and is provided with a cam 15 that abuts the bottom surface of the mounting plate 9. The motor 14 drives the cam 15 to rotate, and when the cam 15 rotates, it will knock on the mounting plate 9, causing the mounting plate 9 and the lining plate 5 to vibrate.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
